Will this project work for Mac OSX?

[daj]

Is this supported on a Mac? I didn't see Mac support mentioned in the README or any issues, and wanted to check if this will work before I go too far down the path of installing all the prerequisites.

The underlying project appears to be supported on Mac, though some custom steps are required, as listed in these guides:
aws-deepracer-community/deepracer-core#11 (comment)
https://github.com/kevinmarlis/deep-racer/blob/master/Mac-Local-Training-Installation.md

I'm using macOS Mojave 10.14.6 with Intel Iris Pro 1536MB.

The init.sh script appears to work, but there were at least two problems with the start.sh script:

• Path /robo/container is incorrect.
• gnome-terminal is not present.

I opened the linked PRs to fix these.

However, even after fixing these two problems, I can't find any sagemaker logs. vncviewer shows a car going around/near a track for a few minutes, before eventually the track and car disappear.

It seems like maybe the rl_coach Docker container is failing to start?

docker ps | awk ' /sagemaker/ { print $1 }' is returning blank. Listing the running Docker processes shows only these two:

$ docker ps
CONTAINER ID        IMAGE                                 COMMAND                  CREATED             STATUS              PORTS                    NAMES

I was able to get Sagemaker to run in a Python virtualenv by following the deepracer project instructions, with one slight tweak: aws-deepracer-community/deepracer-core#78

I would like to get it working via deepracer-for-dummies, as the instructions are much easier to follow...

DETAIL

Here are the outputs of the init and start scripts.

These warnings/errors are output by the init.sh script on macOS Mojave 10.14.6 (not sure if they are benign):

debconf: delaying package configuration, since apt-utils is not installed
...
Warning: apt-key output should not be parsed (stdout is not a terminal)
...
debconf: unable to initialize frontend: Dialog
debconf: (TERM is not set, so the dialog frontend is not usable.)

debconf: (This frontend requires a controlling tty.)
debconf: falling back to frontend: Teletype
dpkg-preconfigure: unable to re-open stdin:

I reviewed the output from init.sh, and these were the only warnings/errors:

Here is the output from running start.sh (includes the code from the two open PRs):

$ ./start.sh

The container is attempting to mount the directory from the host filesystem at this path.

Changing the volume in the compose file breaks this and you end up with this error:
No /opt/ml/input/config/resourceconfig.json
which causes the sagemaker container to fail on startup

[alexschultz]

in order to make this work with a relative path (i.e. the volumes directory in this repo), we need to figure out how to change where the container is trying to mount the "robo" directory.

[alexschultz]

for reference, the code where this seems to break down can be found here:
./deepracer-for-dummies/deepracer/sagemaker-containers/src/sagemaker_containers/_env.py
It tries to configure the environment path in this file.

With the merge of Deepracer-for-Cloud and Deepracer-for-Dummies it is now possible to run on MacOS.

Don't run ./bin/prepare.sh on your Mac M1 :) It will wipe out docker-compose.
